Taiseki (タイセキ) was a shinobi from Iwagakure who fought and died during the Third Great Shinobi World War. He had a quiet and wary personality. He formed a team with Kakkō, using their superb diversionary tactics to attack the enemy. With his Hiding with Camouflage Technique he was able to approach his enemies from their blind spot, easily killing them with a single strike. He confronted Team Minato, led by Kakashi Hatake, during the Third Great Shinobi World War, managing to take Rin captive. He was later killed by Obito Uchiha, however, while he and Kakashi attempted to rescue Rin.
